The effect of vestibular rehabilitation (VR) on anxiety, dizziness and poor balance that developed after cochlear implant (CI) surgery is described. A 54-year-old woman, with profound hearing loss since the age of 2 years, underwent right CI surgery 2 years previously. On implant activation, the patient immediately felt dizziness and imbalance, which affected the ability to perform activities of daily living and increased anxiety to where the patient considered the CI removal. Prior to VR the patient was evaluated with the Dizziness Handicap Inventory and the Visual Vertigo Dizziness Questionnaire and clinically with the Zur Balance Scale and Video Head Impulse Test...

OBJECTIVES: To determine whether relative delays among domains exist in the conversational use of vocabulary, syntax, and morphology by children with cochlear implants (CIs) and whether these were differentially affected by age of implantation (AOI) and the audibility of speech. METHODS: Participants in this short-term longitudinal study were 126 children with AOI of 6-38 months and a matched group of 30 children without hearing loss. Language samples of the same children at ages 3...

OBJECTIVE: The main goal of this study was to determine the knowledge and beliefs of otorhinolaryngologists in a secondary setting in selected economically advanced European countries concerning severe hearing loss, hearing aids, and cochlear implants (CIs). Secondary goals of the study looked into the information sources of the otorhinolaryngologists and into key topics of importance for these professionals. In Europe, many adults, who could benefit from a CI, do not have one despite their availability via national health care systems...

OBJECTIVE: Cochlear implants (CIs) have dramatically improved the lives of children who are deaf or hard of hearing; however, little is known about its implications for preventing the development of psychiatric symptoms in this at-risk population. This is the first longitudinal study to examine the early manifestation of emotional and behavioral disorders and associated risk and protective factors in early identified preschoolers with CIs compared with hearing peers. DESIGN: Participants were 74 children with CIs and 190 hearing controls between ages 1 and 5 years (mean age, 3...

HYPOTHESIS: The decline of low-frequency hearing in people with ski-slope hearing loss varies and might depend on etiology. BACKGROUND: People with ski-sloping hearing loss might benefit from cochlear implantation with preservation of residual hearing. To reduce the risk of losing low-frequency hearing after implantation, the electrode-array can be inserted partially up to the desired frequency. That, however, obstructs electrical stimulation of lower frequencies...

There is clear evidence for cross-modal cortical reorganization in the auditory system of post-lingually deafened cochlear implant (CI) users. A recent report suggests that moderate sensori-neural hearing loss is already sufficient to initiate corresponding cortical changes. To what extend these changes are deprivation-induced or related to sensory recovery is still debated. Moreover, the influence of cross-modal reorganization on CI benefit is also still unclear. While reorganization during deafness may impede speech recovery, reorganization also has beneficial influences on face recognition and lip-reading...

INTRODUCTION: Cochlear implant prosthesis facilitates spoken language development and speech comprehension in children with severe-profound hearing loss. However, this prosthesis is limited in encoding information about fundamental frequency and pitch that are essentially for recognition of speech prosody. The purpose of the present study is to investigate the perception and production of intonation in cochlear implant children and comparison with normal hearing children. METHOD: This study carried out on 25 cochlear implanted children and 50 children with normal hearing...

Hearing loss greatly reduces an individual's ability to comprehend speech in the presence of background noise. Over the past decades, numerous signal-processing algorithms have been developed to improve speech reception in these situations for cochlear implant and hearing aid users. One challenge is to reduce background noise while not introducing interaural distortion that would degrade binaural hearing. The present study evaluates a noise reduction algorithm, referred to as binaural Fennec, that was designed to improve speech reception in background noise while preserving binaural cues...

Deaf learners are a highly heterogeneous group who demonstrate varied levels of academic achievement and attainment. Most prior research involving this population has focused on factors facilitating academic success in young deaf children, with less attention paid to older learners. Recent studies, however, have suggested that while factors such as early cochlear implantation and early sign language fluency are positively associated with academic achievement in younger deaf children, they no longer predict achievement once children reach high school age...

OBJECTIVES: Binaural pitch fusion is the fusion of stimuli that evoke different pitches between the ears into a single auditory image. Individuals who use hearing aids or bimodal cochlear implants (CIs) experience abnormally broad binaural pitch fusion, such that sounds differing in pitch by as much as 3-4 octaves are fused across ears, leading to spectral averaging and speech perception interference. The goal of this study was to determine if adult bilateral CI users also experience broad binaural pitch fusion...

To examine and identify the changing pattern of published articles in the otology literature over the past several decades. We used a variety of search engines available through PubMed.gov based on key words in the following categories: diagnosis, diagnostic tools, and therapeutic tools. The number of searchable key words increased from 1945 to the present. Overall, there has been a major shift in topics cover in the otological literature. Most recently, there has been significant increases in the following categories: age-related hearing loss, speech discrimination, and cochlear implantation...
